I got my Tilt 2 yesterday. I charged it to 100% before using it, then had it on all afternoon setting it up and adding programs. I charged it all night, but when I got up this morning the battery said 70%.
I went to the power settings and noticed there's an information tab that has status info since the last full charge. The status under Last full charge on my phone said "not applicable". I plugged it in at work this morning and waited a while to make sure the charging light turned from orange to green. It did and the battery power remaining was 100%. I left it charging another hour.
A little later I checked the information tab again. It still says Last full charge: Not applicable. HUH???
Aside from the Last full charge field, it also has stats for Standby time, Talk time and Device usage since last full charge. Since I apparently still haven't had a "last full charge" all the values are 0 on my phone.
Does anyone else have a date and time in that field on the information tab?
i got the same on my imagio.
When I first got my Tilt 2, I noticed that screen and thought "hey that's useful". It had the values all filled in properly. But when I went back later to check it, I saw "Not Applicable" just like you. It seems to be intermittent though, because I checked it just now and it has good data. I haven't noticed any correlated factors that predict whether the info will be there or not.

you should never leave your phone plugged into the charger after it has reached full capacity. you're basically draining the overall battery life of the phone, so it won't last as long off of a full charge.
did that to my old tilt before I found out about the overcharging thing, and had to use my warranty to get a new one since the phone would shut off by itself at 90%+ and turn back on again with >5% battery power left

I wasn't really sure that it was fully charged because of that stupid message about the last full charge not applicable. Thanks for the information. I didn't know that it was possible to ruin a battery by overcharging it.
@enisoc,
I thought it seemed like it would be a useful feature, too. Every single time I check power settings the values are null. It's interesting to know you've seen data there at least twice.
ETA: Now that I think about it, for the last two years I've plugged in my Tilt before going to bed and left it charging all night. Every morning it was 100% charged and I never noticed any adverse effects.

Maybe I've just been very lucky, but I have had a Sprint HTC Touch and before that a Samsung Blade (razr wannabe), each for two years. Every night for those four years, I plugged in my phone before going to bed and left it there. I have always had great battery life on both phones.
Specifically for the TP2, I have read that it stops charging at some point when it's done, and won't trickle even if you leave it plugged in. This has been reported by various people because they find that if they leave it plugged in for very long times, they'll end up with only about 95% battery, because after the first few hours it was no longer charging.
Perhaps less convincing, but also interesting, is the fact that (when it works) the "last full charge time" on my TP2 shows up as a couple hours after I went to bed, rather than the time when I unplugged it in the morning.
YMMV

oh wow really? that's interesting. that would be nice if it's really true. what I've been wanting is an app that allows the phone to make some sort of noise (i.e. an alarm sound) when it is fully charged. just to let it's owner know that it's finished and so it won't get overcharged. I think i'll go request it at development n hacking.
I am 100% sure that you cannot overcharge a TP2, in fact I would say any phone or device with a Lithium Polymer battery.
..........
it's true, once the TP2 hits 100% it stops charging the battery & the usage time will kick in.
Day 3 and still no data in the battery power information tab.
do a hard reset. mebbe itll work.
Since its very new, you got nothing to lose.
flip, do you have a TP2? If so, does that tab give you data all the time?
yes, its a Tmo TP2.
it worked on the Stock rom.
I have a custom rom now, and it works as well
once the green light comes on on the touch pro 2 u it stops charging, u cannot overrcharge it
Not only can you not overcharge the lithium Ion batteries it is actually better for them to be recharged as often as possible.
Menneisyys wrote a great article on it a while ago. This confirms what I have always been told.
http://forum.xda-developers.com/showthread.php?t=342162&highlight=battery+charging
Overcharging li-ion (and li-po) batteries results in catastrophic failure, a.k.a. explosion. Therefore, chargers for these battery chemistries stop charging when they're full.
Something is wrong with ne WM6.5 driver!
Yesterday my battery duration was about 24h (with 6.1 i charge it every 2-3 days!)!!
I fully charged at midnight and now, after 15h it says 90%... It's a little bit strange!
At midnight i could see battery stats.. Now it says "not applicable".
I used Dr SigStat and it says a temperature of 2,47°C!!! (in WM6.1 temperature was normal).
What's wrong??
Over the weekend I finally got some data on the information tab. Either Saturday or Sunday morning when I checked it gave some time around 5AM as the last full charge time. Now it's back to Not Applicable.
@D J Palmis,
I wonder if anyone knows the answer to the 6.5 battery dilemma. When I was using a cooked 6.5 ROM on my Tilt I was getting normal battery duration. My battery life on the Tilt 2 is comparable to my old Tilt.
i see this on my tilt2. battery info shows up, with idle/usage times for a short while after full charge (green) if i check after a few hours, it goes to n/a. looks like a driver bug to me.
I have purchesed HD7 4 days ago. It never charges 100% even if i leave it on charge for whole night.
Any solution.
how do you know it doesn't? the battery icon isn't exactly specific? but if it doesn't, take it back to the store you bought it from.
The phone stops charging before 100%
Just like other phones it has battery indicator in the form of cell/battery.
It should appears filled/full when charging is full and as the battery drains it should gradually appears empty. Now the issue is that it never appears full. The extreme right side of the cell/battery always stays/shows empty.
In other words we can say that the phone stops charging before 100%.
Beside this the indicator works fine and the battery life is also ok.
I bought this phone in UK and currently working in dubai so I cannot take it back to the store.
This happened to me, for the past week+ (I bought the phone on 28th).
I don't know why but an Overnight Charge didn't seem to be long enough for it to charge fully, it was always nearly charged.
However, This morning it seems to have charged 100% so maybe it's just a matter of time? Maybe the battery isn't in sync or something when you first buy it.
Think the battery icon is a bit dodge. As long as you get the green indicator light you know it's fully charged. If it's still orange then still needs topping up.
I've not had a problem charging myself but what I have found is that sometime the indicator says it's nearly dead. Reboot and sudenly there is an increase in amount of battery left. Very odd.
Maybe you need to wait a few weeks just to let it settle.

That isn't acceptable for obvious reasons, so I hope that isn't the case.
P.S. 14-30 day return/exchange policies.
All right Dudes!
The problem is fixed. Simply fully charge your mobile phone and then full discharge till it turns off by its own. Repeat the procedure three times and you are done.
Good Luck
I have the same issue, if you turn the phone off and back on when the light turns green, the battery icon is then full.
So seems like a software issue to me.
My HD7 is going back tommorow anyway, keeps resetting itself and when trying to video in 720p it looses focus!
I previously went back to O2 store the day after i bought the phone about the original charging issue. They were going to swap the phone but then had no stock. Then my above issues topped it today so took it back and surprise surprise they were out of stock! Apparantly expecting a delivery tommorow but they don't know what they receive till they get it (BS i reckon) so if they don't have any in tommorow I'm getting a refund and going to go for a Venue Pro or just stick with WM 6.5..

How do you "full discharge" the phone? Use it until the battery is complete dead and charge it up again x3?
Yes, use it till battery is fully dead and charge till charging light turns green.
That never worked for me either, infact last night when the phone was flat, I have left it on charge over night and it went green, but showing about 50% charge, turned it off and back on and its then full.
My phone is doing this as well, now. Charges to full on teh charger. Take it off, adn it goes straight to 75% charge - viewable in the Battery Saver by battery level. It's impossible to charge it fully, and battery life is TTEERRRRIIBBLLEE.
Either something is wrong with the phone or firmware, or the OS. Not sure. But I can't use the phone like this. It's as if it has a 920 mAh battery in it. Obviously that shouldn't require anymore explanation.
---------- Post added at 11:25 AM ---------- Previous post was at 11:14 AM ----------
Follow-Up: I'm convinced it's a bug in the WP7 OS. When you charge to full, and take it off the charger, it instantly drops to 75%, then if you put it back on the charger 20 minutes later it goes to 93%?!
Problem is, the OS is set to shut down service, etc. when battery power is low (even beyond the battery saver setting, IIRC), so the bad information the OS has can hamper usability. It's basically cutting 2 hours off your battery life when you unplug the phone after a full night/day's charge.

And kill the battery, forgot to say.
Charge on the wall charger, not PC USB.
I have now done three cycles now drained to 1% and put on charge over night when I unplug and check the phone it says 98% and drops 2-3% within 5 mins of use. But if I plug it back in it will then go back to 100%. Anyone else?

There have been threads about this already. Batteries, once charged fully, cannot 'keep charging', so they will stop charging until it is low enough to charge again.
This protects the battery from all sorts of nasty and evil things.
^ precisely. Batteries shouldn't be pegged at 100% and continue to be charged. The firmware lets it drain down then charge up again. You can just get 'unlucky' and unplug at a point where its discharging and at 98%.
I remember that happening with the Nexus S. I'm thinking it must be a Samsung thing. It's just one of those weird OEM things like, Motorola phones measuring the battery in 10% intervals.
All manufacturers charge their batteries this way but there are many ways to mask that process. People apparently want to see a fully charged phone when they plug it off the charger. They don't mind that their phone drops to something between 95% and 100% in a matter of minutes as long as it's "full" upon disconneting. Seems Google just displays the correct charge instead of pretending to be on 100%.

Pretty much. The G2 with stock firmware (and from what I remember with the Evo 4G w/ stock), HTC charges to 100%, discharges back to 90%, and charges back up again. etc.. The LED charge indicator turns green at 90% (so according to them, anything about 90% is a "full charge").
You can see this in regular use. There are days where my phone sits at 100% for hours, and others where it only takes an hour to tick down do 99%, even with the same usage. Just depends what "state" the battery is at when you pull it off charge in the morning.

Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.
yes my phone will go from zero to 100% in an hour no problem when using charger that came with phone

Really? Did it charge like that from the very beginning or did it take a few charges to get to that speed? I think it takes me like 1.5-2 hrs from real low to full charge with fast charge enabled.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?
Has this happened to anyone else with charging issues?

I haven't ran into anything like that yet. Who is your carrier? Maybe you can take in your charger and battery to get it replaced? Can you try charging with a different quick charging phone or something to narrow down if it's the phone or charger's fault?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

Weird, I need like 1.5 hrs to get from 15% to full on fast charge and about 1.75 hrs for 15% to full on slow charge.
i timed my 1st charge. 57 min from 0 to 100. phone turned on and screen off.
Yep, to me that's the best feature. No more battery switching.
I even bought the Verizon vehicle charger with fast charge, and it works just as quick

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.
Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P
I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.
I think I can work around that charging schedule. I am also going to subscribe to that magazine now.
Well I dont have much expectations from a 4y old device, but this kinda sudden change is making me curious. I plugged in my phone to the AC mains tomorrow night @ 12 AM @ 5% battery. When I woke up today (@ 7 AM), I just turned off the switch without looking at the charge. When I looked at the charge right now (@ 10 AM), its 77%. My first guess was that some app has drained the 23% battery (I thought it must have charged 100%, anyone will think so if a phone is left to charge for 7 straight hour), but then I had a look at the power statistics (screenshot attached). It just stopped charging after reaching 77%!? Why? It was still plugged in. Anyways, yesterday only I installed Ampere on my phone. Installed because I had doubt that the adapter I had been using for some long time is a fake one. What do you think should be the reason for this type of 'rejecting incoming charge'?
